Subject: [PATCH v2 0/3] refs: cleanup errno sideband ref related functions.

From: "Han-Wen Nienhuys via GitGitGadget" <[email-masked]>
Date: Fri, 23 Apr 2021 15:31:44 +0000

v2:

 * peff's feedback. For now, leave refs.c alone; instead cleanups in
   files-backend and the ref backend API.

Han-Wen Nienhuys (3):
  refs: remove EINVAL specification from the errno sideband in
    read_raw_ref_fn
  refs/files-backend: stop setting errno from lock_ref_oid_basic
  refs: make errno output explicit for read_raw_ref_fn
